Warts are usually viral infections and rarely from a genetic history. They have varied presentation on the skin. Once they appear, it is best to remove them by any of the methods described below depending on the location and other factors. They are usually contagious and can spread to other parts of the body and to other people who are in regular close proximity.
Chemical cautery is a technique of applying caustic chemicals such as trichloroacetic acid (TCA), or salicylic acid to remove the wart.
Sometimes if the wart doesn’t fall in one session a second treatment many be required.
Removal of the wart tissue with liquid nitrogen which causes the freezing of the wart tissue. The blood vessels is freezed which forms a hematoma under the wart and hence a scab gets formed which makes the wart fall off.
Removing wart with radio waves is the most efficient and newer method to remove wart from the skin or mucous tissue. A local anesthesia is applied 45 minutes before the procedure on the lesion. After anesthesia, radio waves are used to go over the surface of the wart, which makes it evaporate. Curettage is needed only on the hands and feet after the radio waves in order to be sure that the root of the wart is removed. Patient goes home with a dressing and it will heal in 6 – 7 days.
Laser removal is a method which uses a laser beam, and the principle of heating and evaporating the wart is the same as in radio wave removal. Healing is somewhat longer than in other methods considering the fact that the skin is damaged more during the intervention.
